TAS5719PHPR Application Field and Working Principle

The TAS5719PHPR is a low voltage, power-efficient, mono digital audio system from Texas Instruments. It is designed for high voltage audio systems and provides an integrated solution for Class-D output stages. The TAS5719PHPR is a low-voltage, power-efficient, mono digital audio system that provides Class-D output stages, typically used in high voltage audio systems. Its specialized architecture provides high-fidelity sound with its low-distortion HDCD and along with a wide range of audio features, it makes it suitable for automotive audio applications.

TAS5719PHPR Operating Principle

The TAS5719PHPR is an integrated full-bridge classified (Class-D) output stage and allows audio enthusiasts to create an optimum system for high-voltage audio applications. The device is based on a voltage-based, pulse-width-modulated (PWM) architecture, which ensures high efficiency and minimal audible distortion by using a low-voltage, high-efficiency power converter. This power converter is responsible for the amplification of the audio signals.The operating principle of the TAS5719PHPR consists of three main components. The first is the PWM control circuit, which is responsible for driving the output power stage. The control circuit produces the switching pattern that generates the desired output voltage level. The second is the power stage which is a full-bridge type configuration in which switching between positive and negative supply voltages is obtained. The third is the hybrid analog-to-digital (A/D) converter which is responsible for converting the input signals into digital audio data.

TAS5719PHPR Applications

The TAS5719PHPR is ideal for automotive audio applications. It is used in many automotive audio systems such as car stereos, subwoofers, and other audio systems. Additionally, it is suitable for use in audio distribution networks for commercial applications such as restaurants, retail stores, and other public spaces.
